The Tender of Union was a declaration of the Parliament of England during the Interregnum following the War of the Three Kingdoms stating that Scotland would cease to have an independent parliament and would join England in its emerging Commonwealth republic.
The English parliament passed the declaration on 28 October 1651 and after a number of interim steps an Act of Union was passed on 26 June 1657. The proclamation of the Tender of Union in Scotland on 4 February 1652 regularised the de facto annexation of Scotland by England following the English victory in the recent Anglo-Scottish war. Under the terms of the Tender of Union and the final enactment, the Scottish Parliament was permanently dissolved and Scotland was given 30 seats in the Westminster Parliament. This act, like all the others passed during the Interregnum, was repealed by both Scottish and English parliaments upon the Restoration of monarchy under Charles II.
